The US has been and still is the primary destination for international professionals seeking advanced study programs. Besides the top educational programs, the ability to continue in the US working legally (OPT see below) to gain important international experience is a strong reason to study in the USA.
In addition to the OPT, students can apply for the H1-B visa (see below) after graduating, which allows them to legally work for a company. In the pass, these were not difficult to obtain if you met all the requirements; however, policies have changed and this visa is more difficult to obtain and renew.
If you have the financial ability or a scholarship and only want to study and then return to your country the US is a top option. NOTE: Some professionals are considering Canada, which has more liberal post-study work visa policies.
Says there are two thousand six hundred eighteen (2,618) accredited four-year colleges and universities in the US. Most operate privately or as part of state governments. The US has no Federal Universities.
A total of 1,095,299 students from around the world are currently enrolled in various colleges of the country and international students make up 5.5 percent of the entire US higher education landscape. According to data provided by the US Department of Commerce, international students were responsible for contributing $44.7 billion to the US economy in 2018.

As an F1 student, you are allowed to work on-campus 20 hrs per week; however, campus jobs are not easy to find. You should always check with the International Student Office to get accurate information and advice.
F1-campus employment is work that that takes place outside of a school campus. Off-campus employment is only available to F-1 students who have completed at least one full academic year of their program of study, and who have an economic hardship that qualifies for the Department of Homeland Security’s emergent circumstances.
Working after you complete your studies is called "Occupational Practical Training", which allows you to work from one to two years. However, you must always consult with your schools's International Student Office who will have the latest accurant information to assist you with an OPT request . Also, I strongly advise you to include this in your "Study Abroad Plan".
